Electronic Beacon File Technical Field

The present invention relates to an electronic vapor file to which a plurality of electronic papers each having a sheet-shaped display unit can be mounted. Background art

With the development of the information-oriented society in recent years, the importance of technologies such as displays and hard copy is increasing. However, paper, which has long been used as a medium for transmitting information, has high portability and storability. Therefore, display media such as CRT and LCD are not sufficient as information transmission media, and paper-like display media with memory has recently been developed.

An electronic vapor file has been proposed as a display medium as described above (Japanese Patent Laid-Open Publication No. H10-171620), and an electronic vapor file in which a plurality of these electronic vapor papers are collectively made into a notebook is also available. It has been proposed (Japanese National Publication of International Patent Application No. Hei 11-502,950). In addition, various reliable recording media are being studied as recording materials for display media (see “Japan Harvard cop y'99,” published by the Imaging Society of Japan, pp. 209 to P.251).

Electronic vapor files do not print characters and images on paper, but rather store them as electronic information that can be easily duplicated and edited, and meet the needs of information terminals in the form of familiar books and notebooks. It was developed to respond. That is, the electronic paper file has a portable and notebook-like configuration unlike a conventional display device represented by a display. Also, unlike personal digital assistants (PDAs: Personal Digital Assistants, notebook personal computers), etc., they have the feature of having multiple display units.

Some of the above-mentioned conventional portable information terminals have a communication function, and by using the communication function, information can be exchanged between the portable information terminals regardless of location. It is possible to take. The exchange of the information includes, for example, transmission and reception of a file, real-time message exchange using a communication tool (Chat: Chat), and the like. In addition, by transmitting a video or the like serving as a conference material to an information terminal having the communication function allocated to each participant of the conference, each participant can use his or her own information without using a white port. However, the above-mentioned portable information terminal has only one A4 paper-sized display screen at the largest because of emphasis on portability. For this reason, it is necessary to divide the screen, for example, when browsing materials consisting of a plurality of pages or inputting data while referring to a predetermined document. The common materials (screens) are displayed on the display screen, such as when exchanging information using the above communication tools or when using the above information terminals at meetings, so that, for example, take notes or browse different pages. Then, it is particularly difficult to secure space for displaying and inputting information used only by each user.

This is one of the reasons that the information terminal stores characters and images as electronic information and cannot replace this portable notebook that is portable but has excellent browsability.

Accordingly, an object of the present invention is to provide an electronic vapor file which has the advantages of books and notebooks, and in particular, solves the display problem of an information terminal that occurs during communication. Disclosure of the invention

The present invention includes the following means to achieve the above object.

In other words, it is assumed that an electronic paper file can be mounted with a plurality of electronic papers having a display function. Here, the communication means transmits and receives data to and from a different electronic paper file, and the page management means designates in advance the electronic vapor to be transmitted in one day and inputs the data to the electronic paper. Up data To the communication means.

Further, the page management means may specify an electronic paper to display the received data and transmit (display) the data received by the communication means to the electronic paper to be displayed.

Therefore, by providing the above means, it is possible to provide an electronic paper file having the advantages of books and notebooks and having a communication function. The electronic vapor file can solve the conventional problem that the display area of the portable information terminal is small.

Further, the page management means designates an electronic paper for displaying received data and an electronic paper for displaying data to be transmitted to different electronic papers, and furthermore, designates both electronic papers. , It can be configured to be arranged in a double spread.

With this configuration, unlike the communication that is conventionally performed by dividing one screen into two, not only can a large area be used by one user, but also data management can be facilitated. is there.

It also has an input function that displays data transmitted from another electronic paper file and an electronic paper that transmits images and characters written to the electronic paper to another electronic paper. There is a configuration in which electronic paper is arranged in a two-page spread. Further, in the configuration in which the electronic paper is detachably attached to the electronic paper file, the management of the data in each electronic paper unit becomes easy.

The page management means may include a cursor drawing means for displaying a cursor indicating that the page is pointing to an area on the electronic paper, or a display restriction means for limiting data that can be displayed by the electronic paper. In addition, there is a configuration that includes a function limiting unit that limits the functions of the electronic vapor.

In this configuration, more detailed function settings can be made, and the electronic paper file can be more easily used.

Further, an identification number for identifying the electronic paper may be given to the electronic paper, and the page management means may transmit the data to the electronic paper based on the identification number. For example, identify the identification number of the e-paper the user wants to send data to. When the page management means obtains data to be displayed by inputting the data into the page management means, the data can be transmitted to the electronic paper designated by the user. Further, in order for the user to easily know the identification number, the electronic vapor file may be provided with an identification number acquiring means for acquiring the identification number.

First, the configuration of the electronic vapor file and the electronic paper file will be described in detail. As shown in FIG. 24, the electronic vapor file 30 is composed of a main body 20 having a signal transmission / reception means 22 and a display light emission control means 23 on a back plate 24, a display drive unit 12 and a display unit 1. The electronic paper 10 with 1 is mounted by connecting terminals 13 and 25. Have been. The main body 20 and the electronic paper 10 are also electrically connected via connection terminals 13 and 25. Further, the main body 20 can be provided with one or more connection terminals 25, and when a plurality of connection terminals 25 are provided, a plurality of electronic vaporers can be connected to the main body 20. .

The display light emission control means 23 transfers the data received from the signal transmission / reception means 22 to the electronic paper 10 as display bit data, and also controls light emission of a light emitting sheet described later. The light emission control referred to here is illumination of only an area to be emphasized, change of luminance of the area, and the like. The signal transfer means 22 is used, for example, to receive data from a personal computer communicably connected or to receive the data from a memory card storing data. Here, as shown in FIG. 25, the display unit 11 includes a display sheet A provided with a predetermined display medium and a light emitting sheet B for illuminating the display sheet A. The configuration order will be described below.

First, a transparent electrode (for example, ITO electrode) A3 is formed on the upper base film A2, and a transparent electrode A5 is formed on the lower base film A6. Display medium (eg, ferroelectric polymer liquid crystal) A4 is applied with a certain thickness. Next, the row electrode A 3 and the column electrode A 5 are bonded so as to face each other and form a lattice, and after the molecules of the display medium A 4 have a predetermined orientation, the polarizing plates A 1 7 Paste from both sides. As a result, the display sheet A is generated.

On the other hand, since the light-emitting sheet B only needs to emit light uniformly over its entire surface, the anode B 2 (common electrode) is formed on the upper base film B 1 and the light-emitting sheet B is formed on the lower base film B 6. A cathode B5 (common electrode) is formed on the cathode B5, and a luminescent medium (for example, organic electroluminescence) B4 is formed on the cathode B5 in a predetermined pattern using an insulating layer B3. The anode B 2 and the cathode B 5 are bonded so as to face each other in a lattice.

Finally, the light emitting sheet B generated as described above is attached to the lower side of the display sheet A so that the light emitting sheet B illuminates the display sheet A. The display medium A4 used in the display sheet A does not need to be limited to the above-mentioned non-volatile material. For example, a microcapsule containing a pigment material that binds to positively charged particles and a substance that binds to negatively charged particles (a substance whose pH is opposite to that of the pigment material) is used as the display medium A4. You can also. The structure of such a microcapsule is described in detail in Japanese Patent Application Publication No. 11-520295.

Here, the display on the display sheet A is performed by matrix control using a shutter function described below. That is, when a predetermined voltage is applied between the column electrode A5 and the row electrode A3 of the display sheet A, the orientation of the molecules of the display medium A4 changes in a direction in which no light is transmitted (the shutter is set to 0 N). The pixel specified by the electrode A 5 and the row electrode A 3 is displayed in black. On the other hand, when a reverse voltage of the above-mentioned predetermined voltage (hereinafter referred to as “positive voltage”) is applied, the orientation of the molecules of the display medium A 4 changes in the direction of transmitting light (the shutter is turned off), and this pixel becomes white. It is displayed as shown.

On the other hand, when a voltage is applied between the anode B 2 and the cathode B 5 ′ of the light emitting sheet B, the entire surface of the light emitting medium B 4 emits light and illuminates the display sheet A. That is, when the light-emitting medium B 4 emits light, a pixel (a pixel whose shutter is OFF) in which light is transmitted is formed.

Since the light-emitting medium B4 is formed in a predetermined pattern as described above, the anode B2 and the cathode B5 of the light-emitting sheet B are formed as grid-like individual electrodes (that is, row electrodes and column electrodes). By changing the voltage applied to each individual electrode, it becomes possible to illuminate only an area to be emphasized, such as a title area.

When the light-emitting sheet B emits monochromatic light, a single-color light source may be arranged uniformly over the entire surface.However, when light-emitting sheet B emits light in full color, RGB (Red Green Blue) light sources are arranged in a grid. Keep it. In the case where light is emitted uniformly over the entire surface, the anode B 2 and the cathode B 5 may be used instead of the individual electrodes as described above.

Next, using Fig. 1, the data (character data, image data, etc.) is displayed on the display 11. The procedure shown will be described.

The user inserts, for example, a memory card 41 storing the contents (data) of a paper collection into the main body 20. Next, as shown in FIG. 24, the user inputs, for example, “2 0” using the page designation means 170 composed of a numeric keypad or the like provided in the main body 20. Then, the page designation means 170 notifies the page management means 18 that "2 0" has been input.

This page management means 18 manages the number of electronic papers 10 connected to the connection terminal 25 of the main body 20 at all times while the power of the electronic paper file 30 is turned on. I have. When “20” is input from the page specifying means 17, the page management means 18 determines the number of electronic papers 10 communicably connected to the main body 20, for example, 10 sheets, and The display light emission control means 23 is notified of “2 0” input from the page designation means 170.

When the display light emission control means 23 receives the notification of the number of connected electronic papers 10 and “20” from the page management means 18, the signal transmission / reception means 22 reads the paper collection 2 Instructs to acquire data from page 0 to page 29 from memory card 41. Upon receiving the instruction, the signal transmission / reception means 22 receives the data from page 20 to page 29, and transmits the obtained data to the display light emission control means 23.

The display / light emission control means 23 stores the character data of the transmitted data of pages 20 to 29 in a character storage means 42 provided in a predetermined electronic paper 10, and stores the image data in the image storage means. 4 Store in 3. The character data includes, for example, a character code such as an ASCII code and character area data indicating an area on the display unit 11 where characters are displayed. The above-mentioned image data is obtained from image form data indicating the form of the image, such as the shape, pattern, and color of the image, and image area data indicating the area on the display unit 11 where the image is displayed. Be composed.

The display light emission control means 23 stores the character data in the character storage means 42 as described above, and also stores the character data of pages 20 to 29 of the dissertation collection on the display unit 1 of the electronic paper 10. Convert character codes to dot data for display in 1. You. The dot data is composed of color data and density data for each dot.

Further, the display light emission control means 23 uses the character area data corresponding to the character code converted into the dot data, and displays the color data and density data of the pixels of the display unit 11 for displaying characters. And a display bit data indicating that When the display light emission control means 23 generates the display bit data, for example, the display light data corresponding to the character written on page 20 in the electronic paper 10 on the first page closest to the cover 26 1 is displayed. The bit data is stored in the electronic paper 10 on the second page.The display bit data corresponding to the characters written on page 11 is stored in the electronic paper 10 on the 10th page. 2 Transmit display bit data corresponding to the characters written on page 9. The display bit data transmitted to each electronic paper is received by the display driver 12 a provided in each electronic paper 10. Upon receiving the display bit data, the display driver 12a generates a pixel for displaying a character and a voltage to be applied to the pixel based on the display bit data.

Subsequently, the display driver 12a applies a predetermined voltage to a pixel displaying a character using the column wiring L2 and the row wiring L1 shown in FIG. As a result, the characters written on pages 20 to 29 of the dissertation collection are displayed on the display unit 11 of the electronic paper 10.

When the display light emission control means 23 obtains the image data written in the collection of pages 20 to 29 from the image storage means 43, the display light emission control means 23 outputs the display bit data from the character data. Generates display bit data from image data as generated. Upon generating the display pit data, the display light emission control means 23 transmits the display bit data to the display driver 12a.

The display driver 12a displays an image on the display unit 11 based on the transmitted display bit data. Therefore, the characters and images written on pages 20 to 29 of the paper collection are displayed on the display unit 11 of the electronic paper 10. When the character storage means 42 and the image storage means 43 are provided in the display drive unit 12 of the electronic paper 10 as shown in FIG. 26, the electronic paper 10 is attached to the main body 20. Yo Even if it is removed, the character data and image data can be stored in the electronic paper 10. However, the character storage means 42 and the image storage means 43 need not always be provided in the electronic paper 10, but may be provided in the main body 20, for example. In the above description, character data and image data are read from the memory card 41. However, even if character data and image data are read from a recording medium such as a CD-ROM or a DVD-ROM or a hard disk of a personal computer, Good.

Next, an editing process for editing characters and images displayed on the electronic paper 10 will be described.

As one mode of the electronic paper 10 that can edit characters and images displayed on the electronic paper 10, as shown in FIG. 2, a transparent sheet 4 with a digitizer function is provided. An electronic paper 10 in which 4 is placed on the upper surface of the display unit 11 can be considered. In this embodiment, the user specifies a color from the color palette displayed on the electronic paper 10 and writes the desired image from the transparent sheet 44 onto the writing implement 14 (a sharp-pointed object). , Pen, etc.), the transparent sheet 44 detects the position of the contact point between the writing instrument 14 and the transparent sheet 44 using the digitizer function. The transparent sheet 44 transmits the detected position of the contact point to the display light emission control means 23. However, if the display light emission control means 23 can detect the shape and position of a symbol drawn by a pointing device represented by a mouse (including a cursor linked to the pointing device), The user may draw characters and images on the transparent sheet 44 using the pointing device. Based on the color and expression method designated by the user (for example, as drawn with a brush or a brush) and the position of the contact point, the display light emission control means 23 determines the shape or pattern of the drawn image. Recognize the position where the image was drawn. The display light emission control means 23 generates display bit data from the recognized image shape and pattern and the position where the image is drawn, and stores the display bit data in the image storage means 43.

When the display bit data is stored in the image storage means 43, the display light emission control means 23, when the display bit data is stored, displays the display based on the storage content of the image storage means 43 after storing the display bit data. Display at 0. In addition, when adding a character to a character or an image displayed on the electronic paper 10, first, the user specifies an area in which the character is to be added using the writing implement 14. The transparent sheet 44 transmits the area designated by the user to the display light emission control means 23. The display light emission control means 23 generates character area data based on the area transmitted from the transparent sheet 44.

Subsequently, the user inputs predetermined characters using a keyboard 46 connected to the main body 20 or a software keyboard mounted on the electronic vapor machine 10. The character code of the input character is input to the display light emission control means 23. Note that the writing instrument 14 may be used to additionally write characters.

In Fig. 11, each electronic paper with a highlighted pattern (dot pattern) indicates a master electronic paper. In other words, the electronic papers 653, 654 are master-electronic papers for the electronic papers 663, 664, and the electronic papers 673, 674. Further, the electronic papers 665 and 666 are master electronic papers for the electronic papers 655 and 656 and the electronic papers 675 and 676.

As described above, if an electronic vapor file with restricted electronic vapor functions is used, for example, at a meeting, user A 6 5 1 writes opinions on electronic vapor 6 5 3 and 6 5 4 The opinion is displayed on the e-papers 663, 664, 673, and 674 of the user B 661 and the user C 671. Also, if the function of transmitting the display contents of the electronic vapor printers 65 5 to 58 8 to other electronic vapors is restricted, the user A 65 1 can use the electronic paper 6 65 to 65 5 The memo written in 8 is not displayed on the e-vapors of user B 661 and user C 672.

By the way, in Embodiments 1 to 6, transmission and reception of only display contents displayed on the electronic vapor have been described.However, conventionally, for example, the above-described communication means 17 is used for transmission and reception of files. Needless to say, it is good.

[Embodiment 7]

In the above, the display contents of the specified electronic paper and the other electronic paper are the same. In the present embodiment, a configuration is described in which the display content of a predetermined group including a plurality of electronic papers is the same as the display content of another group.

First, the user turns on the electronic paper file 100. When the power is turned on, the page management means 18 displays the menu 154 on the cover display section 271 of the main body 20 of the electronic vapor file 100 as shown in FIG.

Note that the page management means 18 does not necessarily need to display the menu 154 on the cover display section 27 1. For example, the page management means 18 may display the menu 154 on a specific electronic paper connected to the electronic paper file 100.

When the menu 154 is displayed, the user selects the “initial setting” 154c of the “system setting” menu 154b from the menu 154 by using a pointing device. Accordingly, the identification number acquiring means 15 2 provided in the main body 20 can be used as the electronic mail shown in FIG. The identification numbers D 101 to 106 of the papers 101 to 106 are obtained from the electronic papers 101 to 106. Here, it is assumed that the electronic paper 101 to 106 is powered on so that the identification number acquiring means 15 2 can acquire the identification numbers D 101 to D 106. I do.

The identification number acquiring means 15 2 sends the acquired identification numbers D 101 to D 106 to the setting means 15 53 provided in the page management means 18.

Next, when the identification numbers D 101 to D 106 are sent, the setting means 153 sets the destination setting menu 154 d on the cover display 271 as shown in FIG. The identification numbers D101 to D106 are displayed.

The user presses the group setting key 154e of the setting menu 154d with pointing / development to perform grouping of the displayed identification numbers D101 to D106. Next, the user specifies the identification numbers D101 to D103 using a pointing device, and presses the enter key 154f.

As a result, the setting means 15 3 groups the identification numbers D 101 to D 103 It is stored as a constituent element of the item 1505a, and further, the identification numbers D101 to D103 are stored in association with the page numbers 1 to 3 in the group 1505a. The above setting means

1 5 3 displays the page number stored here in the destination setting menu 15 4 d. When the page number is stored, the setting means 15 3 stores a frame of a predetermined color around the identification numbers D 101 to D 103 constituting the group 150 5 a as shown in FIG.

1 6 0 is displayed.

Next, the user specifies an area surrounded by a frame 160 shown in FIG. 14 with a pointing device, and further uses a software keyboard to name the group 1505a, for example, “EP 1 ". The setting means 153 stores the input “E P 1” as the group name of the group 155 a and displays it in the destination setting menu 154 d. When the user does not enter the group name, the setting means 153 may arbitrarily set the group name.

In addition, similarly to the setting of the above-mentioned group 155a, the user designates that the identification numbers D104 to D106 constitute one group 155b, and furthermore, as the group name, Enter “EP 2”. Also in this group 155b, the setting means 153 stores the identification numbers D104 to D106 of the group 155b in association with the page numbers 1 to 3 in the group. I do.

The method of grouping electronic papers may be performed by a method other than the above method. For example, the setting means 153 may classify the identification numbers D 101 to D 106 only by the user inputting the number of groups or the number of sheets per group. When the user does not specify the group, the setting means 153 may constitute one group with the identification numbers D101 to D106.

The setting means 15 3 stores the identification numbers D 101 to D 106, the group name and the page number in the group, and stores the electronic vapor data 101 0 1 through the communication means 17. To: 106, the electronic vapor to be written 101: to transmit the group name and page number of 106. Here, the group name “EP1” is assigned to the electronic paper 101 to 103 corresponding to the identification data D101 to D103, and the group name “EP2” is assigned to the identification data D. The electronic vapor corresponding to 104 to D106 is transmitted to 104 to 106.

As shown in FIG. 13, when the communication means 31 of the electronic papers 101 to 103 receives the above-mentioned drop name “EP 1”, the electronic papers 101 to 103 are displayed. The driver 12 a displays “EP 1” at a predetermined position on the display unit 11. Similarly, the display driver 12a of the electronic paper 104 to 106 displays the transmitted drop name "EP2j" at a predetermined position on each display unit 11 in the same manner. By displaying the group name on each electronic paper 101 to 106 in this way, the user can easily identify which group each electronic paper 101 to 106 belongs to. You can check.

The predetermined position of the display section 11 where the group name is displayed may be specified in advance, or may be set when the group is set. Next, a case in which the stored content of the stored group is canceled will be described. For example, the user presses the release key 5 14 g of the destination setting menu 15 4 d using a pointing device, and selects an area surrounded by a frame 160. Then, the setting means 153 recognizes that the setting to cancel the setting content of the group 155a has been input.

Next, the setting means 153 extracts the identification numbers D101 to D103 corresponding to the group name {P1 "from its own stored contents. Then, the group name “E P 1” and the page number stored in association with the identification numbers D 101 to D 103 are deleted.

Since the setting contents can be canceled in this way, for example, even if the user makes a mistake in the grouping, the setting contents can be canceled and the grouping can be performed again. When the setting is cancelled, the setting means 15 3 is transmitted via the communication means 17 to the group 1 whose setting is canceled. The instruction to delete the display of the group name is transmitted to the electronic vaporizers 101 to 103 constituting 55a.

When the communication means 31 of each of the electronic papers 101 to 103 receives an instruction to delete the display of the group name, the display driver 12a of the electronic papers 101 to 103 is activated. Delete the group name displayed on the display section 1 1.

The page numbers in the above groups can be changed by the user as follows.

The user presses the order change key 154h shown in FIG. 14 and selects a predetermined identification number. Subsequently, the user inputs a predetermined page number using the software keyboard, and presses the enter key 1554i. Thus, the setting means 153 stores the page number input here as the page number of the electronic paper whose identification number has been selected above. If the changed page number is stored here as the page number of another electronic paper, the setting means 15 3 sets the page number that is not currently used as the page number of the other electronic paper. Is stored.

Further, the user may assign a name to the electronic papers 101 to 106 so that the name can be displayed on the electronic papers 101 to 106.

For example, a user selects a predetermined identification number with a pointing device or the like, and inputs predetermined characters or symbols using a software keyboard. The input character or symbol is stored by the setting means 153 as a name indicating the electronic vapor of the identification number. If the user does not enter any characters or symbols, the setting means 153 stores the identification number as the name of the electronic paper.

The setting means 153 transmits the name of the electronic paper to the electronic paper storing the name of the electronic paper.

When the communication means 31 of the electronic paper receives the name of the electronic paper, the display driver 12a of the electronic paper displays the received name at a predetermined position of the electronic paper.

Also, a mark for identifying the group may be displayed on the electronic paper so that the user can easily grasp the group to which the electronic paper belongs. In order to realize this, when the user selects the frame 160 shown in FIG. 14 by pointing and device, the setting means 153 shown in FIG. 15 is placed at a predetermined position of the cover display section 271. Display the pull-down menu 1 6 1 for creating a group mark.

From this pull-down menu 16 1 the user selects the color of the mark, for example red. When the user selects a color, the setting means 1553 then displays a drop-down menu 162 from which a mark display method, for example, "always display", "display at regular intervals", and the like can be selected. . For example, if the user selects “always display”, then, the setting unit 1553 sets the display position of the mark, for example, the entire surface of the display unit 11 of the electronic paper, the bottom of the display unit 11, the top, Display pull-down menu 163 for selecting left end, right end, etc. When the user selects the top, the setting means 153 generates display information of "red: always displayed: top". When the setting means 15 3 generates the display information, the setting means 15 3 transmits the display information to the electronic vaporizers 101 to 103 belonging to the group name 150 5 a via the communication person 17. When the communication means 31 of the paper 101 to 103 receives the display information, the display light emitting driver 12a displays the display information. That is, here, the top of the electronic papers 101 to 103 emits red light.

By displaying the display information on the electronic paper as described above, the user can easily grasp the group to which each electronic vapor belongs.

To end the destination setting menu 154d, the user selects "End setting" key 154k using a pointing device. "Setting end" key 1 5 4 When k is selected, the setting means 1 5 3

4 The display of d is stopped, and the page management means 18 displays the menu 15 4 on the cover display section 27 1.

In addition, when adding the electronic paper to be grouped, the user selects “System setting” 15 4 b in the above menu 15 4 again, and selects “Initial setting” 1

5 Select 4c. As a result, the identification number acquiring means 15 2 The identification means of the electronic paper to be newly added is acquired, and the setting means 153 displays the destination setting menu 154d on the cover display section 271, as described above. This transmission destination setting 1 54 d menu displays the identification number of the electronic vapor paper to be added, and the user can use the added identification number as a component of the predetermined group in the same manner as described above. .

As described above, when the electronic papers 101 to 106 are grouped, the user can electronically transfer the data of the dissertation collection from, for example, the memory card 41 in which data for displaying the dissertation collection is stored. Do the work of inputting into the profile file 100.

First, the user selects “data display” 154 m from the above menu 154 by using a pointing device (FIG. 16: S 10).

Next, the user inputs, for example, “100” using the page designation means 170. When the numerical value is input, the page specifying means 170 notifies that “100” has been input to the page management means 18.

When "1 0 0" is input from the page specifying means 170 to the page managing means 18, the identification numbers D 101 to D 106 stored in the setting means 153 are inputted. Get the page name and the group name to which it belongs.

Here, the setting means 153 stores the identification numbers D101 to D106, and the identification numbers D101 to D103 belong to the "EP1" group. The page numbers of the identification numbers D101-103 are 1-3. The identification numbers D 104 to D 106 belong to the “EP 2” group, and the page numbers of the identification numbers D 104 to D 106 are 1 to 3.

Since there are three electronic papers belonging to each of “EP 1” and “EP 2”, the above-mentioned page management means 18 is configured such that each electronic paper group is composed of three electronic papers. Is notified to the display light emission control means 23 that the "1 0 0" has been input to the page designation means 170.

When the display light emission control means 23 is notified that the number is three, the signal transmission / reception means 22 transmits the data of pages 100 to 102 of the paper collection from the memory card 41 to the signal transmission / reception means 22. Instruct them to get them (Fig. 16, S11). When there is such an instruction, The signal transmission / reception means 22 acquires the data of page 100 to page 102 from the memory card 41 and transmits the data to the display light emission control means 23 (FIG. 16, S12).

When the display light emission control means 23 receives the data of the pages 100 to 102, it converts the received data of the pages 100 to 102 into display bit data as described above. I do. The display light emission control means 23 converts the display bit data into display bit data and transmits it to the page management means 18 (FIG. 16: S13).

Based on the page numbers of the identification numbers D101 to D106 obtained from the setting means 153, the page management means 18 discusses the electronic papers 101 to 106 with each other. Send the data of the collection. For example, the data of the 100th page of the collection of papers is transferred to the electronic papers 101, 104 of the identification numbers D101, D104 with the page number 1 as communication means 17 To send over. Similarly, the data on page 101 of the papers is stored in the electronic papers 102 and 105 with the page number of 2 on page 101 of the papers. It is sent to electronic papers 103 and 106 with the number 3 (Fig. 16: S14).

When the communication means 31 of each electronic paper 101 to 106 receives the data for displaying the collection of papers, the display driver 12a receives the collection of papers received by the communication means 31. The data is displayed on the display section 11 of the electronic paper (Fig. 16: S15).

As a result, pages 100 to 102 of the dissertation collection are displayed in group 1555a and group 1555b.

Also, with the electronic papers 101 to 103 and the electronic papers 104 to 106 displaying the paper collections 100 to 102, the user can use the above-mentioned page designation means 17 If you enter “103” using 0, the electronic vapor files 101 to 103 and the electronic papers 104 to 106 will contain pages 103 to 103 from the paper collection. The page will be displayed. That is, even if the content displayed on the electronic paper is changed, the displayed content of each group is the same.

Furthermore, since the electronic papers 101 to 106 can be separately placed on a desk, the user can view a plurality of electronic papers at once. In addition, if a predetermined electronic vaporizer among the electronic papers 101 to 106 has a function similar to that of the main body 20, these electronic vaporizers 101 to 106 can be used. A configuration similar to the above can be obtained only by using the above.

[Embodiment 8]

Embodiment 8 describes a configuration of an electronic paper file such that the display contents of a plurality of electronic paper files are the same.

First, as shown in FIG. 17, the user stores the same data in the character storage means 42 and the image storage means 43, for example, three main bodies 2 10 and 3 10 in which the contents of the same paper collection are stored. , 4 10 One body is selected as the “host”.

As for the method of selecting “host”, as shown in FIG. 3, the host selection menu 180 displayed on the cover display section 27 1 of the main body 210 is selected using the writing implement 14.
